STONE-DRAG.

SPECIFICATION forming part of Letters Patent No. 355,792fdated January11, 1887.

Application filed November 13, 1886. Serial No. 218,774. (No model.)

To aZZ whom it may concern.-

Be it known that I, THOMAS SHAW, of the city and county of Philadelphia,Pennsylvania, have invented a new and improved article of manufacture,known as a Stone-Drag; and

I hereby declare the following to be a full,

thesame with suitable stays, and in the pro vision of a chain-Windlass,in the manner and for the purpose hereinafter described.

The object of the invention is to facilitate the loading of a drag withheavy material and to lessen the friction of hauling and .to lessen thewear and tear.

In order to enable others to use and practice my invention,I willproceed to describe its construction and operation.

On reference to the accomyanying drawings, which form part of thespecification, Figure 1 represents a side view of drag in positionloaded with stone; Fig. 2, a front view of the drag, and Fig 3 a topview of the same.

Similar letters refer to similar parts, of which a. is a flat steelplate, curved on its front end and braced on both sides by flatwrought-iron bracing b, which is firmly riveted to the sheet a and islooped on its rear end, k, in the manner shown, to furnish a hand-hold,and is looped and riveted on forward end, i, in the manner shown, to actas a bracing to the curved front of sheet a.

0 is a cross-bar, riveted to brace at d, Fig.

- 1, to limit forward movement of load.

his an ordinary iron loop for attachment of horses, 8:0. d d areordinary chain-whee1s, secured to ordinary axle, held in bearings c c,which are riveted "securely to sheet a. The said chainwheels act as anordinary Windlass when operated by hand through lever e. Said lever isprovided with a pawl,f, working in ordinary ratchet-wheel g on the axle.A pawl, 71, is

position to receive a heavy object, as the stone Z, for example, when hethrows a loose chain, m, over the stone, and the loose ends of the chainover the two chain-wheels d, when he vibrates lever e by hand, causingthe chainwheels to rot-ate in a slow and powerful manner, enabling oneman to draw the load upon the drag in a speedy manner compared with theordinary method, which generally requires sev ral men for a moreprolonged period.

Heretofore the drugs have been fashioned out ofwood of aflat plankcharacter,the great thickness of which interfered with rapid loading,and the extra friction induced by rough stones on a wood surface greatlyretarded the loading and the hauling of the same, all of which isovercome in my invention.

' "What I claim,'and desire to secure by Letters Patent, is

1. A stone-drag composed of a metal plate curved at its front end andhaving metal strengthening-ribs secured to the side edges of the plate,substantially as described.

2. A stone-drag composed of a metal plate bent at its forward end, andmetal ribs secured to the side edges of the plate, the ribs being bentat the rear to form loops, substantially as described.

3. A stone-drag composed of a metal plate bent at its forward end, andmetal ribs secured to the side edges of the plate, bent to form a bracefor the front curved ends, substantially as described.

4. A stone-drag composed of a metal plate having metallic ribs securedto its sides, the ribs being bent at the rear to form handles and at thefront to support the curved portion of the plate, substantially asdescribed.

5. The combinatiomwith a stone-drag composed of a metal plate with sidesupports or braces and unobstructed rear end for lying flat upon theground, of a Windlass secured to the front and adapted to draw the loadover said end upon the drag, substantially as described.

6. The combination, with a metal drag having braced sides and a fiatunobstructed rear end, of a chain-Windlass supported upon the braced andcurved front end and adapted to draw the load over the rear end upon thedrag, substantially as described.
